GNOME 3.18

What's new for users


Control Center

  • Bluetooth sharing settings moved to the Bluetooth panel, to make them easier to discover.


Kinetic scrolling works with touchpads now

New mouse bindings on scrollbars:

  • Primary click warps to location
  • Shift-Primary click jumps by pages
  • Secondary click starts variable-speed autoscrolling <- this is a new feature

Touch selection

Greatly improved handling of text selection with touch:

  • Bigger, nicer drag handles for modifying text selections.
  • New popovers for cut/copy/paste etc.
  • Fixed RTL appearance
  • Behavioural changes - touch selection defaults to per-word selection, text edition popover is now toggleable by tapping on the selection, ...

Multitouch touchpad gestures

Use multitouch gestures on your touchpad! This feature is only available under Wayland.

List of gestures that are supported:

  • 4-finger vertical swipes to switch workspace
  • Out of the box zoom/rotate support in applications using GtkGesture infrastructure (evince,eog,?)


  • New UI for ongoing operations.

File Chooser

  • New type to search feature, compatible with other GNOME 3 applications.
  • Usable with a touchscreen, thanks to the use of popovers for context menus.
  • Improved feedback about where files are in Recent view and search view.
  • New places view
  • Lots of other polish - better feedback for no search results, repositioned file name entry when saving.


Shared between Nautilus and the file chooser:

  • Other places view - a single location to view local volumes and network locations (known servers, windows networks, avahi networks). This allows the sidebar to be much less cluttered, and is more manageable if you have a lot of these locations.
  • Remote search isn't recursive - doesn't hammer network bandwidth (shared with Nautilus).
  • Updated places sidebar - better drag and drop feedback for creating bookmarks.
  • New UI for creating folders, renaming files/folders.

Google drive support:

  • Google Drive automatically appears as a remote filesystem when a Google is added to Online Accounts.
  • Only works when you are online.
  • Can open natively supported files using your regular apps (such as PDFs, images, etc).
  • Google Drive specific files are opened using the browser (for example: documents, spreadsheets, maps).
  • You can add files to your drive through file paste.


New application that previewed in 3.16. Has now matured, with a number of fixes and features.

  • Improved UI for filtering by font.
  • Update to Unicode 8.0.0.
  • New character category "Letters", which shows locale-specific characters deduced from the input-method settings.


Another new application that previewed in 3.16. Improvements since then:

  • Much improved keyboard navigation
  • Calendar management dialog
  • Many cleanups and bugfixes

To Do

New preview app for 3.18. Personal task manager which follows the GNOME 3 design patterns.


  • Better layout - single line, monospace only. Makes it more compact and easier to read.
  • New controls for changing which boot to view.


  • support for the Overview map (AKA minimap)
  • new plugin: find text in all files in a directory (in the gedit-plugins module)


New preview app for 3.18. Feed reader which follows the GNOME 3 design patterns.


  • New user location dot that can show heading
  • Possible to store and complete against recent routes
  • Support for entering latitude/longitude or 'geoURI' in search bar (And actually seeing that location)
  • Command line option support for using pre-downloaded map tiles (also works when offline)


  • Improved initial setup experience guiding the user through setting up a connection and joining rooms
  • Error handling
  • Bugfixes improving the user experience and updated UI visuals.
  • Paste Service Integration


  • New list view.

  • Add toggle buttons to titlebar to easily filter the main view to show:
    • All
    • Remote or
    • Local boxes
  • Show IP/hostname of boxes under their thumbnails.
    • AllanDay: which is shown - IP or hostname? Are they always shown, or just for remote boxes?

    • ZeeshanAli: For local libvirt boxes, their IP. For remote machines, it's the server part of their URL, which could be either hostname or IP.

  • A switch to disable autosaving for a box in the 'System' settings.
    • AllanDay: so this is a per box setting? Why would someone want to use this?

    • ZeeshanAli: yes.

  • Improved thumbnails and emblems.
  • Enable express installation for Fedora 21 and newer.
    • AllanDay: is this a change that has been made on the GNOME side, or the Fedora side? What type of installation media do you need to use?

    • ZeeshanAli: Mostly in libosinfo but a minor change in Boxes itself was also needed. You use netiso (which is the only installation media available now a days for Fedora anyway).

  • Display system notification on install completion.
  • Add "Restart" button to properties view, for libvirt machines.
  • Add "Force shutdown" option in context and hamburger menu.


  • The browser plugin now supports search.

  • Highlight annotations are finally supported
  • Test annotations can be moved now.
  • The UI for adding annotations have been moved from a hidden tab in the sidebar to a toolbar that can be shown from a toggle button in the main toolbar.
  • Many other improvements in annotations in general.

Firmware Updates

GNOME Software will automatically check for device firmware updates using the Linux Vendor Firmware Service https://beta-lvfs.rhcloud.com/. If updates are detected for your hardware they are securely downloaded and then applied during an offline update.

Ambient light sensor support

If a light sensor is present, GNOME will now automatically adjust the display brightness in order to adjust for the ambient light level.

Can be tested using a ColorHugALS device for those who don't have built in hardware.

Windows 8 compatible hardware is supported.

A switch in the control center's power panel allows automatic display brightness to be turned on/off.

  • Allow binding GListModel implementations to ClutterActor instances, to automatically create actors from objects stored inside models.

  • Improvements all around with regards to input on X11, Wayland, and GDK.


New IDE for GNOME. Initially introduced in 3.16 as an early preview, has received a lot of attention, thanks to a successful crowdfunding campaign. New features since 3.16 include:

  • a new panel system to embed project tree, build targets list, documentation index, symbols list, terminal, perf monitor…
  • Editor shortcuts overview listing keyboard shortcuts, touch and touchpad gestures available in GNOME Builder.
  • more (better) syntax/semantic highlighting
  • improved completion
    • jedi is used for Python and it has some GObject introspection support

Sandboxed Apps

Work has progressed on xdg-app, and it is now an official freedesktop project with releases in several distributions. The sandboxing aspects are still very much a work in progress though, although some initial experimental work is available. There is an official Gnome runtime and SDK with builds available at sdk.gnome.org that you can use to build and host your applications. For now there is only a 3.16 version, but work on a 3.18 version is ongoing.

Once we have initial 3.18 builds I'll write a page with simple instructions on testing this.

Human Interface Guidelines

  • Updated and expanded to include new design patterns.
  • Restructured to be simpler and easier to navigate.
